2x - 4y = -2
2x + 3y = 12

using equation 1
2x - 4y = -2
2x = 4y -2
x = (4y - 2)/2

now plug X into equation 2
2((4y-2)/2) + 3y = 12
multiplying 2 and dividing 2 cancel out leaving us with
4y - 2 + 3y = 12
combine like terms
7y -2 = 12
add 2
7y = 14
now divide by 7
y = 2

knowing that y is equal to 2 we can plug 2 into the first equation

2x - 4(2) = -2
2x - 8 = -2
add 8
2x = 6
divide by 2
x = 3

SO y=2 and x=3

2y - A / 3 equals a + 3 B / 4 solving for y
melamori03 [73]
To solve for y you need to first multiply both sides by 4. This will give you: 4y - 4A / 3 = A + 3B

Next you need to multiply both sides by 3: 4y - 4A = 3A + 9B

Now you need to add 4A to both sides: 4y = 7A + 9B

Now divide both sides by 4:

Y = 7A/4 + 9B/4

Arada [10]

Answer:

7

Step-by-step explanation:

If m was 1, then it would be

4 +8 = 36, which is not true.

If m was 7, then it would be

28 + 8 = 36, which is true.

If m was 11, then it would be

44 + 8 = 36, which is not true.

If m was 36, then it would be

144 + 8 = 36, which is not true.

Hope that helps!
